Petty’s receivers at Baylor, though, have a strong claim as the best offensive unit in the league. The Bears return four players who finished with at least 30 receptions last season, including Antwan Goodley, who produced 71 catches for 1,339 yards and 13 touchdowns in 2013. Baylor will also be adding arguably the deepest and most talented signing class at the position in the country, headlined by ESPN 300 receiver K.D. Cannon.

The Bears, however, aren’t the only ones loaded at receiver.

Texas Tech features the dynamic receiving trio of Jakeem Grant, Bradley Marquez and Reginald Davis, who combined for four touchdowns in the National University Holiday Bowl win over Arizona State. D.J. Polite-Bray emerged over the spring as a downfield burner on the outside. The Red Raiders have also added their top overall recruit from last year to the rotation in Devin Lauderdale, who was forced to attend junior college for a year after failing to initially qualify. Four-star slot receivers Byron Daniels and Ian Sadler will be joining the squad in the summer.

As deep as the Bears and Red Raiders are at receiver, there might not be a positional group in the Big 12 as deep as West Virginia’s running backs.

In their backfield, the Mountaineers have Dreamius Smith (the No. 1 juco back in 2013), Wendell Smallwood (who played as a true freshman), Rushel Shell (who before transferring in from Pitt, set Pennsylvania’s state high school career rushing record), Andrew Buie (the team’s leading rusher from 2012) and Dustin Garrison, the team’s leading rusher from 2011 who had a tremendous spring following a string of injuries the previous three seasons. If that weren’t enough, four-star signee Donte Thomas-Williams will be arriving in Morgantown this summer.

While not as deep, Texas’ three-headed monster in the backfield is more proven than West Virginia’s, though not without questions. Johnathan Gray is coming off an Achilles injury, and Joe Bergeron was barred from the team during the spring due to academics. But when together and healthy, the threesome of Malcolm Brown, Gray (both All-Big 12-caliber runners) and Bergeron is as fearsome as any in the country.

Last fall, the Texas backs ran behind the most experienced offensive line in the Big 12. This season, that distinction belongs to the Sooners, whose offensive line unit caps the poll.

All told, Oklahoma boasts 107 career starts along its offensive line, headlined by senior tackle Daryl Williams and guard Adam Shead, who have been starting since their redshirt freshman seasons. Guard/center Nila Kasitati and tackle Tyrus Thompson are also returning starters on an offense that placed second in the Big 12 in rushing last season.
